From e479660d9dd8bf7017c7dc78ccfa6edd9c51ec7a Mon Sep 17 00:00:00 2001 From: Santosh Kumar Pradhan Date: Mon, 28 Oct 2013 12:46:37 +0530 Subject: gNFS: RFE for NFS connection behavior Implement reconfigure() for NFS xlator so that volume set/reset wont restart the NFS server process. But few options can not be reconfigured dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be restarted.
